OBJECTIVE To define the frequency and predictors of short esophagus in a case series of patients undergoing antireflux surgery. METHOD An observational prospective study from September 10, 2004, to October 31, 2006, was performed at 8 centers. The distance between the esophagogastric junction as identified by intraoperative esophagoscopy and the apex of(More)
BACKGROUND In morbid obesity, optimisation of nutritional strategies impacting cardiovascular and metabolic risk profile is a desirable target in clinical practice. OBJECTIVE To assess in morbid obesity the feasibility, safety and efficacy of a nutritional cycle comprising a short-term carbohydrates-free diet delivered by nasogastric tube followed by an(More)
AIM To investigate the effectiveness of head compensatory postures to ensure safe oropharyngeal transit. METHODS A total of 321 dysphagia patients were enrolled and assessed with videofluoromanometry (VFM). The dysphagia patients were classified as follows: safe transit; penetration without aspiration; aspiration before, during or after swallowing;(More)
SUMMARY The effect of different levels of zinc intake on tumor growth was studied by implanting Walker 256 carcino-sarcoma into weanling Sprague-Dawley rats maintained on laboratory chow or on a zinc-deficient synthetic diet. Three experimental groups receiving this synthetic diet were given 0, 50, or 500 parts per million, respectively, of zinc ion in the(More)
PURPOSE Dysphagia is a symptom of different pathological conditions characterised by alteration of the swallowing mechanism, which may manifest at different levels. We report our experience in the evaluation of the swallowing mechanism with combined videofluoroscopy and manometric recordings. MATERIALS AND METHODS For the combined study, we used a Dyno(More)
PURPOSE This study was undertaken to verify the effectiveness of compensatory postures, suggested on the basis of the type of dysphagia identified at videofluoromanometric (VFM) investigation to ensure safe oropharyngeal transit. MATERIALS AND METHODS Eighty-one patients with amyotrophic lateral sclerosis (ALS) underwent speech therapy assessment and VFM(More)
Absence of the peristaltic contractions in the esophageal body and the failure of the lower esophageal sphincter (LES) post-deglutitive relaxation are the major motor disturbances in patients with achalasia. These alterations are usually evidenced by means of stationary esophageal manometry, which is able to record changes over a brief period. The aim of(More)
AIM To compare the mid-term outcomes of laparoscopic calibrated Nissen-Rossetti fundoplication with Dor fundoplication performed after Heller myotomy for oesophageal achalasia. METHODS Fifty-six patients (26 men, 30 women; mean age 42.8 ± 14.7 years) presenting for minimally invasive surgery for oesophageal achalasia, were enrolled. All patients underwent(More)
BACKGROUND The relation between visceral fat accumulation and development of cardiovascular and metabolic disorders has been demonstrated. The aim of this study was to determine the relationship between a new ultrasound visceral fat thickness (VFT) measurement and clinical and anthropometric data in a consecutive series of obese patients. METHODS(More)
INTRODUCTION The Situs viscerum inversus associated with anomalies of intestinal rotation and fixation is an extremely rare condition. To the authors' knowledge, this is the first report of colon cancer associated with intestinal malrotation and mesenterium ileocolicum commune. CASE PRESENTATION A 34-year-old man with a 2-month history of diarrhea(More)
